Eagle Ford Sweet Spots

Published
American Association of Petroleum Geologists (AAPG)

In highly heterogeneous plays that are geographically extensive, it is extremely important to take a multi-pronged approach that integrates geophysical, geochemical, petrophysical, and geological techniques at every step of the way. Highly heterogeneous reservoirs such as the Eagle Ford are characterized by sweet spots – the sweet spots are often much sweeter than anyone suspected. By the same token, the barren expanses are definitely barren.

How can you find out how to prospect for sweet spots in the Eagle Ford? Try AAPG’s esymposia, short courses, GTWs, and field seminars.

The most affordable of the group – the e-symposium – will be available soon. Prospecting for sweet spots in the Eagle Ford will be the subject of an AAPG E-Symposium taught by Galen Treadgold and to be held on January 20 at 2 pm CST.

The key issue for the exploration companies in the Eagle Ford is finding where to focus acreage acquisition and optimize drilling plans for optimal gas and oil recovery. This e-symposium will first consider the geologic context of the Eagle Ford and then look at geophysical techniques, in particular, comparing and contrasting the value of 3D Processing seismic attributes in building a successful exploration plan. Other topics of discussion will include: seismic data, full azimuth data, high frequency/high fold data and heterogeneities in the Eagle Ford, to name a few.

Galen Treadgold will be explaining how modern seismic data and interpretation techniques can add significantly to the database and greatly enhance regional understanding of the play for many companies. This information will be especially beneficial to those companies exploring the play that have limited availability to conventional subsurface data.

Ultimately, the pursuit of Eagle Ford acreage and the designing of an Eagle Ford drilling campaign is best accomplished through a comprehensive understanding of the geologic framework coupled with a focused interpretation of the seismic. This course will explain how using 3D seismic will magnify the interpretation of the seismic.

Key Topics will include:
  • Seismic data
  • Heterogeneities in the Eagle Ford
  • Isochron and Isopach maps
  • Coherence and curvature attributes
  • Lineaments associated with small-throw faults and possible fracture trends
  • Seismic data offer a number of opportunities to understand potential heterogeneities in the Eagle Ford
  • Amplitude variation implications
  • Full azimuth data
  • Long offsets
  • High frequency / High fold data

Structure of the E-Symposium

Each e-symposium consists of one-hour live e-symposium, along with material for one full day of independent study. The live portion will be followed by a full day of independent study (not a live event). The one-hour live e-symposium can be accessed from any computer anywhere in the world using a high-speed internet connection. After the event is over, you will receive via email information about accessing the asynchronous segment (not live) which consists of your independent study materials, to be accessed and studied at any time. You will be able to email responses to the readings, along with your study question answers for CEU credit (if you sign up for the extended package).
